Performance Library
Case Studies
Explore real-world projects using Elastiko® ECR rubberized asphalt. Filter by state, scan project summaries, and open the official PDF reports to review performance outcomes, construction notes, and agency learnings.
Project evidence you can reference, share, and build from.
Case studies help agencies, consultants, contractors, and plant teams evaluate how Elastiko® ECR performs in the real world. Instead of relying on theory alone, these PDFs document where the work occurred, what was built, and what performance indicators were observed over time.
DICKINSON MI PROJECT
The report summarizes the application of rubber modified asphalt pavement with the dry process. A demonstration project with such dry process was paved in Dickinson, Michigan, in June 2019. Three sections were paved in the project: control leveling mixture and control surface mixture, control leveling mixture and rubber modified surface mixture, and rubber modified leveling mixture and rubber modified surface mixture.
INTERSTATE 35 PAVING PROJECT: LIBERTY, MO
In 2017, The Missouri DOT began an evaluation of ElastikoR ECR (Engineered Crumb Rubber) as an alternative to terminal blend rubber or polymer modification of asphalt binders. Their evaluation included lab testing of modified binders and mixes, followed by mainline paving on I-35 near Liberty, MO.
THIN HMA OVERLAY ON PUMPHREY DRIVE
A thin (1 inch–1.5 inch) hot-mix asphalt (HMA) overlay was constructed on Pumphrey Drive in Fort Worth (FTW) from July 30, 2007, to August 3, 2007. Two Type F mixes were designed for this project following the new proposed balanced mix design procedure using the Hamburg and Overlay Tester test methods.
